Vaping may pull lead and other metals into your lungs

"FDA, the e-cigarette companies and vapers themselves to realize that these heating coils, as now made, seem to be leaking poisonous metals, which then get into the aerosols that vapers inhale". The process creates an aerosol, which contains vaporized e-liquid and tiny liquid droplets. The scientists tested and found the presence of 15 metals in the e-liquids in the coil-containing e-cigarette tanks and in the generated aerosols. Chronic inhalation of these metals has been linked to lung, liver, immune, cardiovascular and brain damage, and even cancers.

Troublingly, the authors also found arsenic in over 10 percent of the sampled e-cigs. They were specifically interested in whether the metal coil that vape pens use to heat the liquid in order to turn it into vapor was leeching or generating toxic metals.

They found that there wasn't much to worry about with the e-liquid itself - there were only minimal levels of unsafe metals like lead, chromium, and nickel and manganese.

Eugenie Bouchard wins lawsuit against US Tennis AssociationShe is now ranked 116th, well outside the ranking cut off for the main draw, but said she was hoping to receive a wild card. Bouchard, once ranked No. 5 in the world and a Wimbledon finalist in 2014, was forced to withdraw from the U.S.

In the aerosol samples, nearly 50 percent of them had lead concentrations higher than health-based limits defined by the Environmental Protection Agency.

Although minimal levels of metals were found in the e-liquids within refilling dispensers, the metal contamination transferred to aerosols produced by heating the e-liquids. Their use has increased 900% among high school students from 2011 to 2015, according to a 2016 report from the Surgeon General and more than 9 million adults vape regularly, according to the Centers for Disease Control and Prevention.

But recent studies have found some e-cigarette flavours contain toxins that harm the body and another found vaping leaves people more susceptible to pneumonia. Moreresearch must be done to determine possible health affects. Unlike the metals, arsenic was present in the liquid, liquid in the dispenser, and aerosol alike.

So, the team began a new project studying the latest devices, called Mods, as well as the aerosol inhaled by smokers.

Researchers at John Hopkins University asked 56 daily e-cigarette users - recruited from vaping shops and conventions around Baltimore - to lend them their tank-style devices. It has come to light that e-cigarette vapours contain a significant amount of toxic metals, which can be risky.

"We know there are many young vapers that have never smoked", Dr. Rule said.

The scientists in the study concluded that exposure to heavy metals was not a significant health concern for people switching from tobacco to vaping, but was an "unnecessary source of exposure" for people who never smoked before.
